ms-van3t compilation fails on Ubuntu 24.04 LTS

[francescoraves483]

The ms-van3t build process seems to fail on the new Ubuntu 24.04 LTS.

Specifically, after configuring the project with "./ns3 configure", the build fails with the following error due to one of the asn1c-generated header files:

[0/2] Re-checking globbed directories...
[1/3570] Building CXX object src/automotive/CMakeFiles/libautomotive-obj.dir/helper/simpleCAMSender-helper.cc.o

  147 | #define SIZE_MAX  ((~((size_t)0)) >> 1)
      |                                  ^
...

Unfortunately, I am unable to test it right now, but we should see if adding a conditional check eventually solves the issues:

#ifndef SIZE_MAX
#define SIZE_MAX ((~((size_t)0)) >> 1)
#endif
